Title: Image forming device
Inventor: KONNO HISAO
IPC: G03G15/00
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To start a register roller at a high speed by a stepping motor without causing step out by approximating a speed up to reaching a prescribed speed from starting time of the stepping motor to an almost (1/n) degree function (n>1) to time. SOLUTION: A register gear 41 is coaxially and directly connected to a register roller 40, and the register gear 41 meshes with an idle gear/pulley 42. The idle gear/pulley 42 is extended to a motor pulley 44 directly connected to a stepping motor 45 by hooking a timing belt 43 on the pulley side. Control of 1-2-phase excitation is performed on the stepping motor 45 by a pulse signal outputted from a control part 46. A pulse rate is set so that a speed up to reaching a prescribed speed from starting time of the stepping motor 45 approximates to, for example, an almost square root function to time after starting. An overshoot of the register roller 40 at starting time is restrained, and the occurrence of step out caused by the overshoot is restrained.

Filed: 1990-11-13
Abstract: PURPOSE:To suppress a through-current without causing a problem in signal transfer time by connecting a parallel circuit comprising P, N-channel transistors(TRs) between a P-channel TR and a power supply of a CMOS inverter circuit and conducting one TR. CONSTITUTION:P, N channel TRs 1, 2 connected in parallel are connected between a power supply VDD and a TR 3 in P, N channel TRs 3,4 comprising a CMOS inverter and the TRs 1,2 are controlled by a CMOS control circuit 11 whose level is fully moved between the power supply and ground and either of them is selectively turned on. Then, in the standby state, the TR 2 is turned on and a source 9 of the TR 3 reaches a voltage at a smaller level from a power supply voltage by a threshold voltage because the N-channel TR is used for the TR 2, a through-current is small even when the TRs 3,4 are simultaneously turned on, then the through-current is decreased without giving an effect onto the signal transfer time thereby reducing the power consumption.

Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To arbitrate the using right of a bus without introducing system down. SOLUTION: When a processor 12 outputs 'bus use request' to a bus arbiter 20 by a signal br12 , the bus arbiter 20 shows 'bus use permission' by a signal bg to give the processor 12 by way of a processor 11. When the processor 12 cancels the 'bus use request', 'bus use permission' which is not received by any processor is left outputted but a conversion means 21 inputs this 'bus use permission' and validates bus under-use information BBSY to inform the bus arbiter of 'a bus is under use'. The bus arbiter 20 receiving 'a bus is under use' cancels 'bus use permission'.

Title: Group iii nitride semiconductor light emitting device and its manufacture
Inventor: KOIKE MASAYOSHI
IPC: H01S5/323
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To form a quantum box having an appropriate size by forming the well section and barrier section of an active layer in specific compositions so that the lattice constants of the well and barrier sections may respectively fall within specific ranges. SOLUTION: An active layer 6 has a quantum box structure. A light emitting device has a sapphire substrate on which a buffer layer is formed. The active layer 6 is constituted in such a state that well boxes 61 composed of Ga0.8 In0.2 N are scattered at nearly regular intervals in a barrier layer 62 composed of Al0.05 Ga0.95 N. Since the ratio of the lattice constant a1 of the Ga0.8 In0.2 N to the lattice constant a2 of the Al0.05 Ga0.95 N is larger than 0.02 (|a1-a2|/a2=0.0228), the Ga0.8 In0.2 N does not grow in a laminar state on the Al0.05 Ga0.95 N layer, but in scattered islands. Therefore, the characteristics of the active layer 6 as a quantum box are improved and the manufacture of the layer becomes easier.

Abstract: PURPOSE:To prevent the ringing of an alarm tone due to the unexecution of alarm mode reset operation by starting an alarm mode by the setting operation of an alarm mode setting part and resetting the alarm mode by a signal outputted from a clock part. CONSTITUTION:A set key 14 on the alarm mode setting part 1 is depressed, and while vertically turning an operation control 13, the time display of reset time is adjusted to the reset time of the alarm mode. Thereby, time data displayed on the reset time 12 are outputted by a dip switch on a reset time setting part 2, transferred to a memory part 3 through a control part 8 and written in a data storage area. The control part 8 controls the operating states of a code storage area in the memory part 3, a decision part 6, an alarm generating part 7, etc., based upon the depression of the set key 14. Thereby even when a door is opened without resetting the device after the lapse of the reset time of the alarm mode, the generation of a trouble generating an alarm tone and confusing the neighborhood can be prevented.
